such as oscillating or reciprocating parts and the like. 1

The invention has primarilyjfor its object to provide means such as a pad adapted to become saturated with'bil fed thereto in any desired manner, thereby causing the various movable parts of a mechanism coming into contact with the pad to become'properly lubricated.

With the foregoing in view the invention consists in what is herein shown and. described andmore particularly pointed out and defined by the appended claims. -While l have shown and described one specific embodiment of the invention, itwill be understood that various modifications and changes inthe details'of construction and arrangement of parts are contemplated as within the scope of the appended claims.

"In the drawings:

Figure 1 is a transverse sectional view illustrating one application of the'invention, the same being taken on the line 1-1 of Figure 2, and s Figure 2 is a sectional view taken on the line of 2-2 of Fi re 1.

At the present timeconsiderable dificulty is experienced in properly lubricating certain movable parts in various types of mechanisms, it being customary to either periodically oil such parts, or, in such cases as the mechanism permits, to direct a constant supply of oil to the same. Both of these methods are objectionable, for the reason that in cases where the movable mechanism is oiled periodically, the same will quickly work out of the movable parts, leaving them dry. Furthermore, constant attention is re.-

tit)

quired in this form of lubricating. In cases where the mechanism is lubricated by a constant feed, a great waste of'oil is present.

The present invention, which is designed to overcome the foregoing disadvantages, is applicable to various types of em the pad 6, the

v the Purpose tillustration, I have .E SlioWI the same in connection with a i oscillating levers ljourhalledfori a aft 2,

which'iscarried by acenti'al bearing'3. The

outer endskof the oscillating lever 1 have pivotedthe'reto a pair of links 4 which are actuated by mechanlsm, not shown. In order 'to properly "oil the shaft 2, the central bear provided with an oil hole 5. f

- be present invention consists inthe pro;v

vision of a porous'pad' 6, which is preferably:

formed from a heavy layer of felt, or similar materialfthe samebeing positioned above the mechanism and supported by the central bearing 3and oscillating arms 2.

lnithe. present embodiment of the invention. I have shown the entire mechanism covered by a hood 7, which serves to carry an oil feed coupling consisting-of a sight feed 8 provided with a regulating screw' 9 which serves to regulate the feed. The oil feed coupling is provided with a threaded extension 10 extending through the hood and secured thereto by means of a nut 10'. lit will be noted from the drawings that the oil feed is positioned directly above the bearing 3 and in alinement with the oil hole 5. Thus as the oil drops from the feed coup-ling to point of greatest saturation will be directly over the oil hole' 5, and the pad being in contact with the bearing 2 will, through capillary attraction, feed a steady supply of oil through the oil hole to the shaft 2.

In operation the feed coupling is so regulated as to permit sufiicient supply of oil to keep the entire pad 6 Well saturated. Thus it will be seen that as the levers 1 oscillate, their ends willcontact with the pad and will take or suflicient amount of oil to lubricate the link connections. p

Connecting the feed coupling and a source of oil supply, not shown, is a feed line 12 which is provided with the conventional type desired to clean the filter or remove the hood 1 7 As previously stated, the oil may be sup- I plied by either a forced feed or by means of ravity.

rom the foregoing, it will be seen that a very simple and economical arrangement has sisting of a bearing, a shaft supported in said bearing; an oscillating lever carried on said shaft; a pad supported by said mechanism and adapted to intermittently contact with said oscillating lever, and means for supplying lubricant to the pad.

2. In combination with a mechanism consisting of a bearing providediwith an oil hole, a shaft supported in said bearing, and an oscillatin lever carried on said shaft; a pad supporte by said mechanism and adapted to intermittently contact with'said os cillating lever, and means positioned practically above said oil hole for supplying lubricant to the pad.

3. In combination with a mechanism consisting of a bearing, a shaft supported in said bearing, an oscillating lever carried on said shaft and members operably connected to the ends of said lever; a pad positioned above and supported by said mechanism, said pad being adapted to intermittently contact with the end of said lever, and means for supplying lubricant to the pad.

4:. In combination with a mechanism consisting of a bearing provided with an oil opening, a shaft supported in said bearing,

' an oscillating lever carried on said shaft, and a member operably connected to one end of the lever; a pad positioned above said mechanism and supported thereby, said pad being'adapted to intermittently contact with the end of said lever, and means positioned above said pad and in vertical alinement with said oil hole for supplying lubricant to the bearing.

In testimony that I claim the foregoing I have here-unto set my hand at Milwaukee, in the county of Milwaukee and State of Wisconsin.
